Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Cystic fibrosis (CF) is a chronic disease that significantly affects an individual's lung function. Antibiotic medications have been proven effective at reducing Pseudomonas aeruginosa (PA) infection, which is one of the main causes of death in individuals with CF. The purpose of this study is to compare the effectiveness of treatment based on quarterly culture results versus consistent quarterly antibiotic treatment at reducing PA infection in children with CF.

The study has two objectives/aims: Aim 1: To test the efficacy of the intervention among adult smokers with cardiovascular disease, pulmonary disease and diabetes mellitus related illnesses (later modified to Chinese adults with and without diseases); and Aim 2: To examine a set of measures (background, general health, psychosocial, and smoking process) that are associated with smoking cessation at 6 and 12 months

Randomized, placebo controlled trial evaluating efficacy of dexamethasone in preventing sleep related breathing disturbances in lowlanders with chronic obstructive lung disease travelling from 700 m to 3200 m.

This study will compare the efficacy of indacaterol versus placebo (i.e., rescue medication only) and tiotropium in patients with Chronic Obstructive Pulmonary Disease (COPD) who have not received maintenance COPD medication for at least 12 months prior to entry (described hereafter as "maintenance naïve", see inclusion criteria).

The purpose of this study is to determine whether pro-adrenomedullin (Mr proADM)in addition to clinical evaluation is effective to predict outcome of acute exacerbations of COPD patients visiting the emergency room(ER).

To study the effects of early exercise training in hospitalized patients for Chronic Obstructive Pulmonary Disease exacerbation (COPD). Interventions are randomized. In one group, early exercise training (aerobic and strength) during hospitalization for COPD exacerbation followed by exercise training at home until 30 days to discharge and in the other the intervention is usual care. In both groups, usual respiratory physiotherapy techniques during hospitalization and adequate physical activity recommendations have been included. The main variable is the increase in moderate or vigorous daily physical activities at 30 days after discharge.

The purpose of this study is to prospectively evaluate the safety and efficacy of the AeriSeal System in patients with advanced Non-Upper Lobe Predominant Heterogeneous Emphysema.

Chronic Obstructive Pulmonary Disease (COPD) is a common lung disease, affecting 1.2 million people in the United Kingdom (UK). COPD patients suffer with episodes of worsening breathing symptoms called acute exacerbations (AECOPD). Exacerbations occur more often as the disease progresses and are a leading cause of emergency hospitalisation. Patients recovering from exacerbations are at high risk of deteriorating, with one quarter readmitted to hospital within thirty days. COPD thus imposes immense burdens on the National Health Service and patients. This research will investigate the effects of using humidified nasal high-flow (HNHF) during recovery from severe COPD exacerbations. HNHF delivers warmed, humidified air under flows of up to 60 litres per minute through a nasal interface. This has been shown to improve clinical outcomes, including exacerbation frequency, hospitalisations, breathlessness and quality of life amongst COPD patients with respiratory failure. It is thought to achieve this by improving secretion clearance and providing positive airways pressure which supports the breathing system. Patients admitted to St Thomas' Hospital, London with COPD exacerbations will be recruited. Prior to discharge, participants will be randomised to receive either usual care alone or usual care plus a HNHF device, which they will be trained to use for a regular period daily. Usual care includes inhalers, steroids and may include antibiotics. Participants will be followed up for 30-days after hospital discharge using weekly assessments, daily symptom diaries and wrist-worn watch-like devices that detect physical activity. This will enable evaluation of the clinical effects of HNHF on re-exacerbations, readmissions, breathlessness, physical activity and quality of life. Device usage will also be quantified. Participants who receive devices will be interviewed to explore their experiences. After the 30-day home follow-up period, a sub-group of participants will undergo detailed breathing tests during and after exercise to explore the effects of HNHF on the respiratory system.

This trial will evaluate the effect of acetazolamide (375 mg per day) vs. placebo on lung water content by ultrasound at acute altitude exposure in patients with Chronic Obstructive Pulmonary Disease (COPD).

Delivery of inhaled short-acting bronchodilators (SABD) is standard of care in the emergency department (ED) for exacerbation of COPD, the goal of such being rapid reversal of airflow obstruction. However, current guidelines for the delivery of SABDs in spontaneously breathing patients make no distinction whether these medications should be delivered via metered dose inhaler (MDI) or jet nebulizer (JN), the specific medication delivery device having no significant effect on hospital admission or reversal of flow obstruction. However, advancements in nebulizer design, namely FDA-approved vibrating mesh technology, have demonstrated significant improvements relative to JNs and metered dose inhalers in efficiency and amount of drug delivered in in vivo and in vitro studies. Currently there are no clinical trials comparing the use of vibrating mesh nebulizers (VMN) to JNs and their effect on clinically important outcomes. This prospective randomized controlled pilot trial seeks to determine if there are differences in hospital admission due to COPD when a vibrating mesh nebulizer is used versus a jet nebulizer.
